With regard to Dr Hertz' letter, there seems to be some confusion in her reading of the article. It was distinctly stated that initial breast-feeding involved infants being frequently brought to the breast, the frequency depending on the mothers' enthusiasm. This was before phototherapy was started; and hence, should not interfere with the efficacy of breast-feeding. The possibility that relative dehydration, as evidenced by the greater weight loss during this period, was a contributive factor could not be excluded.
